I have a Maple tree which broke about four feet up with the heavy snow in Vancouver about 4/5 years ago. It appeared it had an internal hollow spot weakness. So we cut the tree down to the stump. Then the next year new shoots started to grow. I read somewhere that a new tree wouldn’t grow, well it would grow but would need to be trimmed back to nothing each year because it would not be strong. Well as you can see I let one shoot grow and kept trimming back all other shoots. As you can see the new tree has been growing strong for several years now, but it does seem the spot it has grown from is possibly perilous??? I worry if this winter has a lot of snow and or wind it would break. How can I keep this Maple safe? I thought maybe I should trim back part of the stump, so that maybe the new tree will grow around the stump??? Or maybe??????? Really need advice, such a strong determined tree.
